GRAIN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 498,388, dated May 30, 1893.

` Application tiled October 28, 18.92.

To aZZ whom if may concern.; Be it known that I, HENRY HAMPER, acitizen of the United States, residing at Greenville, in the county of Montcalm andStateof forth overthe screen surface for the purpose v of keeping the yopenings of the screen free from obstructions. v f

The object of this'invention istoprovidea simple and efficientA mechanism wherebya reciprocating motion isfimpartedto the traveling cleaner. v l f In` the accompanying drawings consistingv4 of two sheetsz-Figure .l isa sideelevation of f a grain separator provided with my improve.- ments. Fig. 2 is a horizontal section' inline 2 2, Fig. l. Fig. 3 isa longitudinal section of the lowerl part of vthe machine containing the shaking screen, the plane ot' section being taken in line 3-3,Fig. 2. Fig. tis a cross section of the shakingshoe, nwhich the screen is mounted, andconnectingparts," in line 4 4, Fig. 2.1looking forward; Y Fig is a similar cross section in line 5-5, Fig. 2.

Like letters of reference referto llike parts in the several figures.

A represents the stationary frame of the 1nachine,"and B the shaking shoe supported therein by hangers b, or other Swell known means. I C -v l C represents the` fan-and D D the air trunks which are of any suitable construction.

E represents thev screen which is arranged in the shaking shoe or frame in the customary manner. The.shaking shoe is actuated by a horizontal shaft G, supported in bearings at the head of the stationary frame, and

' by one or more eccentrics and rods g g.

vH represents the travelingcleaner'which is arranged upon the screen and whichl moves transversely back Vand forth overthe same, so as to free the' openings of the screen from kernels of grain or other substances which may have lodged inthe same.' This cleanerv consists of longitudinal strips lh arranged at Seralll0|450,24=0. (No model.) y

suitable distances apart to practically coveror reach kthe entire screen surface during the reciprocating movement of the cleaner,

and wiping or cleaning contrivances attached t to the strips `which may be chains t', as rep'-v yresented inthe drawings, or brushes or iieXin bleA strips. The longitudinal strips hare y y connected byav transverse cross bar J, which is securedfto the-upper sldeslof the strips "about midway betweentheir endsV vand bya gguide' barjK, which kis s'ecuredtransversely,lo A the upp'er'sides ofthe strips neantheirlower ends.' f This guide bar rmoves transversely Vbetween two fixed guide'barsltsupported by hangersL from 'the fan 'case or someother 4 Vstationary part of the machine. p v l"'lvIrepresents-a horizontal ratchet wheel y y which is pivoted or .journaled` on'adepende Y ing bracketm secured'tovthe stationary frame yofthe machine. This ratchet Wheel' is'ar-ll (if ranged vabovethe screen on one sidev thereof I f f vand inline with the-cross bar'J. Y .I

ch is attached tok 1 t t 75v Y ratchet wheel and turns the samev forwardly ny is arractuating pawl wh the shaking shoe and which engages with the during the forward ymovement ofthe shaking v shoe.

'O represents a detent vrpa-vvlzwhich hung to thebracket on which Vthe ratchet wheelfis journaled and which engages with'vthe'ratchet wheel land prevents. backward movement thereof. y y l' if P represents a transverse rodv whichfis kattached eccentrically .to the ratchet wheel and connects the ratchet wheel with thetcross bar J of the'cleanerandwhich movesthe cleaner' back and forth across the screen as the 'ratchet wheel rotates. t

The rapid reciprocating motion of the shaking shoe produces, by means of this mechanism,a comparatively slow intermittent rotary motion of the ratchetwheel which in turn produces a slow and intermittent reciprocating motion of the cleaner. The latterY is guided transversely inthe guides attached to the stationary frame but rests loosely on the screen surface, so that thecleaner chains or vother devices bear upon ythe screen surface and cectually prevent the openings thereof IOO from -becominglled with grain or other ob` n structious.

The actuating mechanism of the cleaner is positive in its action, so that, when thecleaner encounters heavy obstructions, for instance sticks which have lodged in the holes ot the perforated plates, the cleaner will not stick but will dislodge or break the obstructions. n I am aware that traveling cleaners are old and that they have been operated by various kinds of mechanisms and I do not broadly claim the same.

I claim as my invention- 1. The combination with the stationary frame, the reciprocating shoe or frame in which the screen is mounted and the cleaner, of a ratchet wheel journaled on the stationary frame, an actuating pawl attached to the reciprocating shoe or frame and engaging the ratchet Wheel, and an eccentric connection whereby the intermittent rotary motion of` y the ratchet wheel is transmitted to the cleaner y HENRY HAMPER.
